I think the point of OP is that while laptops are fine for business trips, tethered usage is superior. My setup is a laptop. Both at home and as work I have a solid desk with an ergonomic chair. On the desk are thunderbolt docks, the docks have hooked the keyboard I like, 2 monitors on mobile stands. And that's it. I have most the advantage of a desktop while using the same machine. One cable to unplug. Super nifty.
